| 英文摘要 | This paper shows quantitatively the consequence of adsorbed water on N-2 or O-2 adsorbed on LiLSX lithium exchanged low silica X zeolite. In the range of 0 similar to 32 H2O/u.c. (unit cell), water present in LiLSX sharply declined the capacity for N-2 or O-2 adsorption. The reason is that the adsorption mainly occurs on the Li+ ions on the 32 SIII sites in LiLSX. When H2O molecules residual after the desorption of hydrated LiLSX are adsorbed tightly on Li+ at SIR site, they block the adsorption of nitrogen or oxygen. Water molecules introduced from outside into the dehydrated LiLSX influence the adsorption of nitrogen less seriously than the residual water molecules do, because of the heterogeneity of adsorption sites and the diffusion behavior of water in LiLSX. When diffused into the inner part of a LiLSX particle, some water molecules may adsorb on weaker sites other than the strongest SIII sites. |
